This sounds like some kind of graphics card issue .. if you see any text
that says 'booting CentOS' or a line at the bottom or the '7' grey boot
screen, you are past the Grub2 stage.

Are these machines running X windows and a Desktop Environment.

If I had to guess, this is an AMD graphics issue .. or possibly another
brand of card.
